Gun-control measures that seemed destined to become law after the school shootings in Newtown, Conn., are in jeopardy amid a fierce lobbying campaign by firearms advocates.
Despite months of negotiations, key senators have been unable to find a workable plan for near-universal background checks on gun purchases — an idea that polls show nine in 10 Americans support.
Another provision that garnered bipartisan support — making gun trafficking a federal crime — could be gutted if Republican lawmakers accept new language being circulated by the National Rifle Association.
The failure of those two measures would be a major setback for the White House and its allies, who have acknowledged that two other proposals  — bans on assault weapons and high-capacity ammunition magazines — are not politically viable.
